The game is almost perfect, the graphics are absolutely amazing. The big amount of cars and tracks are going to keep you busy for a long long time, the career mode is amazing and well designed, but outside driving there isn't anything that makes you really think you are getting somewhere.
The best way to play this game is with a steering wheel as this game is a pure racing simulation. Every track can be driven at any time of the day with snow, rain, heavy rain, fog, etc... The only problem with this game is that some cars are not easy to control without the right setup and you will probably need to spend many hours finding the best setup for each track, and also the fact that this is not a racing game meant for playing on a controller. ( what I want to say is that it is not easy to adjust the controller as perfect as in GT Sport, Dirt, Grid )
